LAMP FILLER AND INDICATOR.

SPECIFIGATION- forming part of Letters Patent No. 279,278, dated June 12, 1883.

Application filed March 10,1883. (No model.)

To all whom it may concern.-

Be it known that I, AARON RING, a citizen of the United States, residing at Maplewood, in the city of Malden, county of Middlesex, and State of Massachusetts, have invented a new and useful device for filling lamps and indicating when they are suificiently full, of which the following is a specification.

In the accompanying drawings, Figure 1 is a perspective, Fig. 2 a top view, and Fig. 3 a vertical section, of the device through the center of funnel, air tube, and flange, showing the cross-bars in the air-tube and wire connection from float to indicator.

Similar letters refer to similar parts throughout the several views.

My invention consists in the use of a float, A, which will rise with the liquid when the lamp is nearly full, connected with an indicator, B, at the top of the funnel T by means of a wire or other suitable connections. The wire is carried up from the float A to the indicator B in an air-tube, O, of suitable size, on one side of the funnel T. This air-tube has two crossbars, X, one near the top and one near the bottom of the air-tube,with a small hole in the center of each cross-bar X for the wire to slide up and down in holding the float A and indicator B in their places. This air-tube C may extend above the top of the funnel T far .enough to prevent spatterings falling into it from the funnel, and below far enough to protect the float A from the falling liquid while the lamp is being filled, leaving the float A free to rise with the liquid.

The float A can be made of cork or thin sheet-metal soldered air-tight, or any suitable material. The indicator can be made of cork or any light substance suitable for the purpose, and colored any bright color readily seen by the person filling the lamp. A flange, D, is soldered onto the funnel and air-tube at a suitable distance from the bottom to allow it to rest on the top of a common-size lamp, thus holding device upright while filling the lamp.

A wire, E, is secured on the outer edge of this flange, the end of the wire turned up for the purpose of hanging the lamp tube and burner on while filling the lamp. This flange D is made slightly concave, with the concave side up, so that any drippings from the can falling upon it will run in toward and down openings near the junction of the funnel and air-tube into the lamp.

The funnel, air-tube, and flange can be made of tin-plate or any suitable material.

To use this device, take out the lamp-tube and hang it on the wire E on the flange, put the funnel into the lamp, and pour the liquid into the funnel till the indicator B rises above the top of the air-tube, when the operator Should cease pouring as the lamp is full enough to allow the replacing of tube and wick.

The funnel through which the air-tube passes and into which the liquid is poured can be made of any convenient shape suitable for the purpose. The opening F at the bottom of the funnel should be large enough to allow the liquid torun into the lamp as fast as it runs'out of the can-spout; so there will not remain any liquid in the funnel to run into the lamp after you cease pouring.

I am aware that funnels have been used to fill lamps with. This I do not claim separate andalone; but

What I do claim, and wish to secure by Letters Patent of the United States, is

1. In a lamp filler and indicator, the combination of the funnel T, tube 0, the wire and its float A, and indicatorB, as set forth.

2. In a lamp filler and indicator, the combination of the funnel T, having the flange D, the tube 0, and the wire with its float A and indicator B, as set forth.
